Quantitative measurement of a mixture of mesophases cubic MCM-48 and hexagonal MCM-41 by 13C CP/MAS NMR

The C-13 CP/MAS NMR was used to quantify a mixture of cubic MCM-48 and hexagonal MCM-41 mesophases by means of interpretation of their surfactant organization, which cannot be determined by X-ray diffraction (XRD) techniques. (C) 2004 Published by Elsevier B.V.
